Answer 2

To evaluate the expression (a-4)^-2a(3a-4) when a = 0.2, we substitute the value of a into the expression and perform the necessary calculations. Let's go step by step:

Step 1: Substitute a = 0.2 into (a-4)^-2a(3a-4): (0.2-4)^-2(0.2)(3(0.2)-4)

Step 2: Simplify the expression: (-3.8)^-2(0.2)(0.6-4)

Step 3: Evaluate (-3.8)^-2 (raise -3.8 to the power of -2): 0.06578947368(0.2)(0.6-4)

Step 4: Simplify (0.6-4): 0.06578947368(0.2)(-3.4)

Step 5: Multiply the numbers: -0.00473684211(-3.4)

Step 6: Simplify the expression: 0.01610526374

Therefore, when a = 0.2, the value of (a-4)^-2a(3a-4) is approximately 0.01610526374.
